FEATURES
The Selective Radiation Meter (SRM) is a hand-held frequency selective
measuring device designed for safety analysis of high frequency
electromagnetic fields. Broadcasting equipment operators and radio
network providers, measurement services, and authorities can use the
SRM to selectively detect individual telecommunications services and
evaluate them according to applicable standards.
The SRM comprises a basic unit plus measuring antenna. The basic
unit contains a spectrum analyzer covering the frequency range from
100 kHz up to 3 GHz. It can be combined with antennas from Narda or
from other manufacturers. Isotropic (non-directional) measurements in
the range from 27 MHz up to 3 GHz can be made using the Narda three
axis antenna, covering everything from VHF radio up to W-CDMA and
UMTS services.
The combination of basic unit plus antenna is portable, robust, battery
operated, and provides all the functions needed for evaluating, storing
and documenting the results without the need for an external PC.
Results can be uploaded to a PC for archiving.
APPLICATIONS
The SRM was specifically designed as a hand-held measuring device
for electromagnetic field safety requirements. It is equipped with tailor
made operating modes for the preferred applications, but it can also be
used for general field strength measurements, just like an ordinary RF
spectrum analyzer. The preferred applications are:
Comparison measurements in known field environments
These are often needed at so-called “shared sites”, where several
mobile phone operators share a common antenna site. The SRM
indicates the overall field strength and the contributions made by the
individual services, either as absolute values or as a percentage of the
permitted limit value. Operators, authorities, and measurement service
providers can then demonstrate on-site that immission safety limit
values are being adhered to, or they can determine which operator
needs to reduce transmission power, and by how much, in order to do
so.
Survey measurements in unknown field environments
These are needed wherever a major field source cannot readily be
identified, but immission limit values still have to be adhered to, such as
at the workplace, in public or private areas, or for particularly sensitive
protected areas like kindergartens, schools and hospitals. Authorities
and measurement service providers can use the SRM not only to check

Subject to change without notice
whether the applicable limits are being adhered to, but also to get a
rapid overview of all the field sources in the frequency range of interest
that may be relevant to human safety.
Individual telecommunications service measurements
Controlling field emissions is the responsibility of every service provider.
With the SRM, it is possible to selectively detect every transmission
frequency used and every occupied channel of the particular service,
even in a complex field environment and in close proximity to other
strong emitters. The results can be integrated over the frequency range
used by the service, displaying the overall result as an absolute value or
as a percentage of the applicable limit value. It is also possible to
determine the field emission that would occur if all traffic channels were
operated at full load by extrapolation from the field strength of a control
or pilot channel operated continuously at full load.
OPERATION
The SRM basic unit comprises a spectrum analyzer with RF input stage,
measurement and operating computer, input panel and display. This
means you can set all functions and values directly on the device, using
the menus, number keys, softkeys or the rotary control. According to
your choice, the SRM also calculates and displays the results directly
• as field strengths or as percentages of the permitted limit value,
• for a single source or an individual channel,
• as a list of sources or channels,
• as the proportion due to a telecommunications service, or
• as the proportions due to all services and their percentage
contributions to the overall exposure level.
The SRM automatically uses the following data for this:
• Antenna factors to convert the antenna output voltage into field
strength values
• Weighting curves specified in current immission safety
regulations and standards
• Telecommunications service frequency range assignments
The “SRM-Tools” PC software supplied with the device as well as the
optional “SRM-TS” PC software provide fully editable tables for
antennas and cables from other manufacturers, user-defined weighting
curves, and lists of telecommunications services. These can be
uploaded to the SRM using the serial or USB interface.

Measurements using the Narda three-axis antenna
These automatically yield isotropic (non-directional) results. There are
basically three ways of making such measurements:
• Antenna directly connected to the basic unit
Measurements of the entire mobile telephony frequency range can be
made like this. Particularly useful in areas where access is difficult,
such as antenna masts, where you need to hold and operate the
device and antenna with one hand.
• Antenna connected to the basic unit by cable
This is useful when you are searching for the location of the highest
field strength by sampling a specific part of the volume inside a room.
• Antenna fitted on tripod, connected to the basic unit by cable
This arrangement gives the most precise results, since the field being
measured is not influenced by either the device or the person making
the measurement.
Measurements with the Narda single-axis antenna
You can use a single-axis antenna to measure in three spatial axes with
the SRM. You just need to align the antenna axis with the three mutually
perpendicular axes one after the other using a special attachment on a
tripod. The SRM saves the result for each of the three axes and then
calculates the resulting field strength.
Measurements using other manufacturers’ antennas
Also, no problem with the SRM. The antenna factors can be uploaded to
the basic unit using the PC software provided.
Spatial averaging (option)
The “Spatial Averaging” function of the SRM lets you take the average
of results recorded at different points in a room or space. The SRM
determines the root mean square value (RMS), giving the average
power level.
Averaging (time averaging)
The field strength measurement results can be averaged over a
specified number of results or over a specific time, such as the 6 minute
period stipulated in many standards.
Time controlled storing (option)
The SRM can store measurements under timer control by specifying the
start date, start time, measurement duration, and other parameters.

OPERATING MODES
The SRM is designed for everyday use and is equipped with general
and special measurement modes tailored to its main applications.
SPECTRUM ANALYSIS
In a multi-frequency environment, “Spectrum Analysis” mode gives you
an overview of all the frequency components and their field strengths.
You only have to set the desired frequency range. The SRM will only
allow you to set values that are within the frequency range of the
antenna connected to it. The spectrum is displayed as a trace, which
can be rapidly assessed to analyze the field situation by means of
marker and zoom functions. Peak value tables show all the field
strengths that exceed a specified value together with the corresponding
frequencies.
The ability to integrate the results over a user-definable frequency range
is a special feature, which you can use to display the power level of a
transmission channel having a bandwidth greater than the selected
resolution bandwidth (RBW). The broadband level can be determined by
integrating over the entire frequency range.
Spectrum analysis mode allows you to identify all
the field sources that lie within the selected
frequency range.
SAFETY EVALUATION
The SRM displays the field strength results as tables in this operating
mode. These are arranged according to individual telecommunications
services, with the overall exposure also shown. You can define the
services yourself. The results can be displayed as a percentage of the
limit value specified in the relevant immission safety regulations, or you
can switch to show absolute values in V/m, A/m or W/m2 and mW/cm2.
“Safety Evaluation” mode gives you an immediate overview of the
contributions made by individual services to the overall field strength.
This is useful in the event of any dispute that may arise when several
providers share the same antenna location.
“Safety Evaluation” mode is based on spectrum analysis followed by
integration over specified frequency ranges. The measurement is
completely automatic. The SRM measures over the entire frequency
range of all the selected services, automatically setting the resolution
bandwidth (RBW) to suit the narrowest bandwidth service in the
process. It stores the selectively measured absolute field strength
values, evaluates them according to the selected regulation and also
saves these results. Individual contributions are determined by
integration over the individual service frequency ranges. The SRM
collects the results for the frequencies between service bands together
(Others) and includes this in the overall result (Total).

UMTS P-CPICH DEMODULATION (option)
In “UMTS P-CPICH Demodulation” mode, the SRM can decode the pilot
channels (P-CPICHs, Primary Common Pilot Channels) of every UMTS
cell detected within a 5 MHz UMTS channel.
The device produces the corresponding results in the form of a table
arranged according to the scrambling codes used to identify the different
cells. The SRM shows the results as a percentage of a limit value or as
absolute values in V/m, A/m or W/m2 and mW/cm2. Along with the sum of
all field strength results from the demodulation (Total), the SRM
determines the total analog channel power (Analog) for the UMTS
channel being evaluated. At the same time, the SRM also shows the
instantaneous values (Value) and the maximum values that have
occurred for each cell since the last reset.
UMTS channel selection is by entering the center frequency or the
relevant channel number. To make it quick and easy to identify the
different scrambling codes, you can select user-defined cell name tables
that assign a user-defined alphanumeric comment to each scrambling
code.
The UMTS P-CPICH Demodulation option allows
the SRM to decode all the pilot channels
(P-CPICHs) within a 5 MHz bandwidth UMTS
channel and assign the measured field strengths
to each UMTS cell on this basis.
TIME ANALYSIS
In “Time Analysis” mode, the SRM measures the field strength values at
a settable center frequency using a resolution bandwidth which can be
selected between 6.4 kHz and 6 MHz. The measurement algorithm
ensures that the results are recorded continuously, processed, and
stored in real time (corresponding with the internal sampling rate).
You can select between PEAK and RMS detectors in “Time Analysis”
mode.
Using the PEAK detector, the instantaneous (ACT) or the maximum
(MAX) value can be displayed numerically. Using the RMS detector, you
can additionally take the average of the measurement values (AVG) or
of the maximum values (MAX AVG) and display these results
numerically. You can set the averaging time between 0.96 seconds and
30 minutes. The “6 minute average” required by many standards is
therefore no problem.
The SRM uses steep cutoff channel filters in “Time Analysis” mode to
selectively monitor a specific service over a period of time without being
affected by the other services.
The SRM measures the peak value or the RMS
value over a period of time in „Time Analysis“
mode. This enables you to make a record of
the variation of field strength versus time.
Monitoring over a time period using “Time Controlled Storing” (option) is
a useful additional feature.
